What is the purpose of a Textile UV Protection Performance Tester?

The Textile UV Protection Performance Tester is a professional instrument used to evaluate the UV protection performance of textiles. Its main applications include:

Measurement of Ultraviolet Protection Factor (UPF):

Directly measures the UPF value of textiles to determine whether they meet the requirements for “UV-protective products.”

For example, according to China’s national standard GB/T 18830. a product can be labeled as UV-protective only if UPF > 40 and UVA transmittance < 5%.

Calculation of UV Transmittance (T%):

Measures the transmittance of UVA (320–400 nm) and UVB (280–320 nm) separately, quantifying the material’s ability to block different UV wavelengths.

Support for Product Development and Quality Control:

Widely used in the development, manufacturing, and market supervision of products such as sun-protective clothing, outdoor apparel, umbrellas, and tents, ensuring that actual protection performance matches product claims.

Compliance with International Testing Standards:

Testing is conducted in accordance with domestic and international standards such as GB/T 18830. AATCC 183. PREN 13758. and AS/NZS 4399. ensuring product compliance and market access.

How does a Textile UV Protection Performance Tester work?

The Textile UV Protection Performance Tester quantitatively evaluates the UV-blocking performance of textiles through scientific measurement. Its core evaluation indicators include UV transmittance (T%) and the Ultraviolet Protection Factor (UPF).

The operation of the instrument is based on spectral analysis and energy ratio calculations, and its working process can be divided into the following key stages:

1. UV Light Source Emission Stage

The instrument is equipped with a stable UV light source (such as a deuterium lamp or mercury lamp), capable of accurately simulating ultraviolet radiation in sunlight.

The emitted spectrum typically covers the full wavelength range from 280 nm to 400 nm, including:

UVA (long-wave UV, 320–400 nm)

UVB (mid-wave UV, 290–320 nm)

These are the primary UV bands affecting human skin.

2. Uniform Irradiation of the Sample

The UV light beam generated by the source is collimated through a precision optical system, including lenses and a monochromator, to form parallel light.

This light is then directed and uniformly projected perpendicularly onto the surface of the textile specimen, which is securely mounted on a dedicated sample holder.

3. Transmission Signal Collection and Detection

When UV radiation passes through the textile, the fabric attenuates the radiation through absorption, reflection, and scattering. The remaining UV radiation that is not blocked penetrates the sample.

The detection system typically consists of:

An integrating sphere, which efficiently collects transmitted light from all directions

A high-sensitivity spectral detector, such as a photomultiplier tube (PMT) or a spectrometer

The detector captures the transmitted light signal and precisely analyzes the spectral energy distribution at different wavelengths.

4. Data Processing and Parameter Calculation

The system software compares the detected transmitted spectral energy with a pre-calibrated incident (reference) light spectrum, point by point, to determine the UV transmittance T(λ)% at each wavelength.

Based on built-in international or national testing standards (such as GB/T 18830. AATCC 183. and EN 13758), the instrument then performs weighted integration and mathematical processing across the full spectral range to automatically calculate:

What are the technical features of the Textile UV Protection Performance Tester?

Comprehensive Spectral Coverage:

The instrument strictly covers the ultraviolet wavelength range of 280–400 nm, enabling precise analysis of both sub-bands:

UVB (290–320 nm), primarily responsible for skin sunburn

UVA (320–400 nm), mainly associated with skin photoaging

This allows accurate evaluation of a textile’s protective performance against different types of UV radiation.

Wide Compatibility with International Standards:

The equipment design and software algorithms strictly comply with major global testing standards, including but not limited to:

GB/T 18830

AATCC 183

This ensures that test results are internationally recognized, comparable, and suitable for global market access.

High Efficiency, Automation, and Intelligence:

The testing process is highly automated and user-friendly. After the test is completed, the instrument or its supporting software can automatically generate and clearly display a full set of data reports, including:

This fully meets the textile industry’s needs for efficient and accurate performance in product quality control, new product development, and certification labeling.
